A BestBuy employee is "confirming" that Sprint is about to carry the iPhone. And a formal announcement about the carrier welcoming the iPhone to its 4G network could come as early as next month's WWDC conference, which - as we learned today - will kick off June 7th with a keynote address from Apple CEO Steve Jobs. So will Jobs unveil the Sprint iPhone at the conference?

According to coverage today from Redmond Pie, which amalgamates a variety of morsels of information from sources and leaks, the employee confirming the Sprint iPhone works at a Best Buy outlet in Pennsylvania, although a particular store was not cited as it would violate the company's "privacy policy." Nonetheless, the source claims that shelf displays will surface within a time-frame that appears to neatly coincide with the start of the WWDC.

Historically, however, Best Buy employees are notoriously left in the dark regarding major announcements and product releases. Even ahead of the iPad's release, very few credible stories - or even leaks - were traced back to Best Buy and the store's myriad workers. Apple, however, does have a stellar relationship with Best Buy and, for this reason, it isn't altogether inconceivable that an employee could be privy to advanced information - either by accident or design.

Without question, a 4G capable 4th generation iPhone would be a massively appealing reality for millions of current or potential smartphone buyers. But for the very reason that some say its simply "too good to be true," perhaps we will have to concur with that assessment until more concrete evidence of a Sprint iPhone surfaces in the days and weeks to come.
